+-4 The Schedule referred to in these' Letten Patent and making pnt' 111e meL To qll whom. ift-may concern:

= Be it known thatl, GEORGE B. Tonnara., of the l cityand -Statepoi' NewYork, have invented, nmde, and

applied to use, a certain' new and useful Improvement in Coolers for Beer and other Liquids; and I do hereby declare the following to be a full, clear, and ex'act de-v scription ofthe said invention,- rcfereuce heilig had to theA annexed drawing, making part of this specih'cation, wherein- Figure 1 is a vertical section of my improved cooler, at the line x :cof Figure 2, which is a side elevation of said cooler.

Similar' marks of reference. denote til-esame parts. 1n Letters Patent, hunted to J. L. Baudelot, November 1, 1859, a vertical range ofcireular pipes is prorided, overwhich the beer', orotherliquid, trickles and passes from one pipe to :mother by a .series ot' dou-'n` ward projections. My present invention is an improvement upon the aforesaid Letters Patent.v

In the use of round pipes for a beer-cooler, the

liquid flows rapidlyover the pipes, and is but little detained in contact with the cooling-suriccs, because tlie liquid trarels a semicircle in passing around they pipe, and 'the capillaryitlractionhasLbutlittle power' to detain the liquid, and cause an accumulation, in the form of a iiscid stra-tuin, of some thickness, adhering to the under portion of the pipe.

The nature of mysaid'invention consists in a series oi' horizontal tubes, inA a vertical or nearly veItica-l range, said tubes being fiat-tened, so as to be Considerably wider in their horizontal diameter than in their vertical diameter, by moans ot' which the following` new and useful features are attained by my said cooler:

' Firs t, a cooier, having the same extent of cooling; surface, can be plafied in much .less space vertically, and thereby require a less head of water for its supply.

'A' round pipe, when ilatteued,-has the lsame area of surface, but a range of flattened pipes, ofthe same a1-ea, will not stand as high as a range of the same number vof circular pipes, the space between the two forms of pipes corresponding.

Second, the sectional area of the water-way through the cooler will be lessened by the flattening of the pipes, and less water-will be requiredin cooling the beer or other liquid, because a larger cooling-surface is obtained,- in proportion to' the capacity of the apparatus, for'the iiow ofthe cooling-liquid.

Third, in agiven space, my present apparatus can contain a larger number of pipes, and present a greater extent of cooling-surface, than in apparatusheretofore made.

Fourth, with a definite supply of liquid to be cooled, upon this apparatus there will be the same quantity running oiithereii-om, but there will be a greater quantity of liquid u pou the surface of the apparatus than with circular pipes; hence the time consumed by cach particleqfrliquid in tricklingT from the top to the botl tom of the apparatus will be increased, and the cooling-liquid will .have a better opportunity to abstract the caloric. This increased quantity .of liquid sus- `tained bythe surface oi' the apparatus is due to two causes: first, that the apparatus itself has a greater area ot'suiface, in proportion to the water-way, in the tubes; and,- second, that gravity does not act so'rap.`

idly nponthe liquid, 'to cause the same to run with as much speed, while upon vthe flattened upper surface of the pipes, as when the pipes are round; and when the liquid isruuning along the under surfacespf the pipes, the cohesive attraction holds the liquid inthe pipe against the actionof gravitation; hence, at these portions ofthe apparatus, the stm-tum of liquid is much thicker than on the other portions ot' the pipe, or upon a circula-' tube.

Fifth, the liquid to be cooled, passing in a stra-tuur along the under surfaces oi' thepipcs, is in the best position 1in heilig cooled; because its caloric rises int-o aud is-absorbed by the cool water in the pipe above that stratum of liquid. '.llius the heat passes rapidly.

upwards from the liquid to be cooled into the coolingliquid, in accordance with the laws governing the ansmissiou ot' head..

If'ind, practically', that a greatsaving of water isv eii'ec'ted in my said appalatuefand thc liquid to be cooled is reduced in tempemture more rapidly and thoroughly than heretoibre.

In the drawing, o a are standards, sustaining the dis`tributingtrough b and sprinkling-trough c, from which the liquid runs withnntbrmity upon the upper 'pipe-'of the range of pipes al, and passes, from one to the other, ti-om the rangesofdownward projections -i,

-and is received in tlicpau c, at the bottom.

' The pipes ofthe range' are connected to 'each other atjalternate endsfso that water supplied at thelowest pipe in the-range circulates through the same, upward,

Aand passes off-fiom' the vupper pipe.

The pipes in such range are attened, as shown, for the purposes aforesaid, and the relative proportion ot' vertical and horizontal diameters' of said tubes may vary, according to the positionand size-of thetubes and the capacity of the'apl'iaratus- I lind, however, that tubes, ofau elliptical section, with the horizont-al diameter about twice and a half the vertical diameter, will act reliably.

What I claim, and desire to secure by Let-ters Pat ent, is-

A cooler, for beer and other liquids, formed of a series of'attened tubes, with their longest diameters horizontally, substantially as specified, so that the stratum of liquid passes in the manner described.

In witness' whereof; I have hereunto set my signa ture, this 2d dav ot'April, A. D. 1868.
